[ARM] 3523/1: Serial core pm_state
|
|
This fixes two problems triggered by the MMC stack updating clocks:
- SPI masters driver should accept a max clock speed of zero; that's one
convention for marking idle devices. (Presumably that helps controllers
that don't autogate clocks to "off" when not in use.)
- There are more than 1000 nanoseconds per millisecond; setting the clock
down to 125 KHz now works properly.
Showing once again that Zero (http://en.wikipedia.org/wiki/Zero) is still
an inexhaustible number of bugs.

We need to be able to have a "SPI bus 0" matching chip numbering; but
that number was wrongly used to flag dynamic allocation of a bus number.
This patch resolves that issue; now negative numbers trigger dynamic alloc.
It also updates the how-to-write-a-controller-driver overview to mention
this stuff.

Add spi_device hook for LSB-first word encoding, and update all the

This driver turns a PXA2xx synchronous serial port (SSP) into a SPI master
controller (see Documentation/spi/spi_summary). The driver has the following
features:
- Support for any PXA2xx SSP
- SSP PIO and SSP DMA data transfers.
- External and Internal (SSPFRM) chip selects.
- Per slave device (chip) configuration.
- Full suspend, freeze, resume support.

Some protocols (like one for some bitmap displays) require different clock
speed or word size settings for each transfer in an SPI message. This adds
those parameters to struct spi_transfer. They are to be used when they are
nonzero; otherwise the defaults from spi_device are to be used.
The patch also adds a setup_transfer callback to spi_bitbang, uses it for
messages that use those overrides, and implements it so that the pure
bitbanging code can help resolve any questions about how it should work.

Patch from Andrew Victor
The serial_core already manages the power state of the UARTs, and
therefore it shouldn't suspend a UART which was previously suspended.
This patch modifies serial_core only call the UART-specific
power-management function if the PM state is actually changing.

An earlier commit (75cf7456dd87335f574dcd53c4ae616a2ad71a11) changed an
overly-zealous PCI quirk to only poke those VIA devices that need it.
However, some PCI devices were not included in what I hope is now the full
list. Consequently we're failing to run the quirk on all machines which need
it, causing IRQ routing failures.
This should I hope correct this.
Thanks to Masoud Sharbiani <masouds@masoud.ir> for pointing this out

I introduced this way back in 2.6.13 when adding the port lock logic.
This device talks out through different "ports" all at the same time, so
the lock logic was wrong, preventing any data from ever being sent
properly.

If the device is disconnected while serial_open() is executing and
either try_module_get() or the device specific open function fails, the
kref_put() call in the 'bailout_kref_put' label will free the memory
pointed out by 'port'.
The subsequent dereferences in the 'bailout_kref_put' label will be
invalid.
The fix is just to assure kref_put() is called after any 'port' usage.

It's become apparent as machines get faster that the emagic kernel firmware
loaders (based on the ezusb loader) have a reset race. a 400MHz TiBook
never tripped it, but a 2GHz Pentium M seems to hit it about 30% of the
time. The bug is seen as a hung USB box and the kernel error:
drivers/usb/misc/emi62.c: emi62_load_firmware - error loading firmware:
error = -110
The patch below inserts a delay after deasserting reset to allow the box to
settle before a new command is issued. This affects only device startup.

661FX7MI-S motherboard which uses the SiS 661FX chipset. The patch adds
an entry to mii_chip_info for the transceiver.
The PHY ids were found using the sis900_c_122.diff patch from
http://brownhat.org/sis900.html but that patch didn't solve the problem,
because the PHY at address 1 was already being chosen.
Without my patch, when bursts of packets arrive from other hosts on a
LAN, the interface dropped one roughly 10% of the time, causing
retransmits. There were fifth second pauses in refresh of large xterms,
and it made Netrek suck. I can provide further test data.
Workaround in lieu of patch is to use mii-tool to advertise
100baseTx-HD, then force renegotiation.
I wasn't able to identify the actual transceiver, so the description
field is a guess.
This patch is similar to Artur Skawina's patch:
http://marc.theaimsgroup.com/?l=linux-netdev&m=114297516729079&w=2
I'm not sure, but I wonder if it means the default behaviour should be
changed, so as to better handle future transceivers.
Diff is against 2.6.16.13.
